How unpack b2container in Gears 5

[jakmrk88]

Hello. Does anyone know how to extract b2container files in Unreal engine in Gears 5. I would like to extract text for translation.

[jakmrk88]

Gears 5 uses oodle compression for b2container.
The GearGame.b2index file contains information about B2 container names, file names, and their location and size in b2containers.
There should be localization texts in Launch.b2container.
Could someone create a bms script to unpack the files?

Did you manage to extract all files successfully with the ravioli tool? Because for me it gives some .riff files and I can't go further than that.

The b2index file contains very important info. Maybe the lack of that info is what causing deficient archives. I am also working on that with python scripts now.

Does the b2container include audio files as well?
Because i'm interested into dump all the voicelines/music from Gears 5, but to my knowledge as of right now, it is not possible to do so...
Thank you for any suggestion!
